This invention relates to agricultural land reclamation.

The purpose of the invention is to improve the operating conditions.

FIG. 1 shows the drainage mouth of FIG. 2, the same, top view.

The orifice tube 1 is laid with a cable and placed in the casing 2 The protective cover 2 is made one-third the length of the perforated and laid in the outflow 3. The total area of perforation 4 of the casing 2 is greater than or equal to the flat section of the wellhead 1. The bottom of the protective casing 2 is placed in a protective cushion 5 in the bottom of the channel, made of tamped rubble. On top of tray 3, an asbestos-cement corrugated sheet 6 or a reinforced concrete plate with a cut-out under the casing 2 is supported.

I The device works as follows.

1The excess moisture of the soil through drainage pipelines (single heat or collector), wellhead pipe 1 and through the perforation of the protective casing

2 and tray 3 enters the channel. At the same time, an increase in the slope of the wellhead pipe: would facilitate the movement of water; this leads to a decrease in siltation and coarseness of

In the spring flood, the mouth is flooded, air is not allowed to enter the meanness of the pipes and there is no pipe coagulation. Spout of water through the perforation of the protective cover eliminates the erosion of the bottom and the opposite slope of the channel.

The construction of the estuary is carried out in the following manner.

An orifice tube 1 is inserted into a protective casing 2, manufactured under stationary conditions, which is guided by a lower end into the channel bottom and equipped with a tray 3. Above the tray 3, asbestos cement corrugated sheet 6 or a reinforced concrete slab is installed to prevent the soil from falling down around the channel bottom. crushed stone is crushed 5. Due to the use of the protective casing 2 and its placement into the bottom to a depth of 0.2-0.3 m and the slope 7 of the channel to a depth of 0.2-0.5 m, the work on the leveling of the channel slope is eliminated, which leads to the preservation of the ecology of the surrounding Wednesday, sokra volumes of handicrafts. The mouth can be equipped in the winter period, and it is also possible to use its machines for cleaning channels from sediments and vegetation.
